首先制备出高比表面积(1000m2/g)、平均孔径在50nm的稻壳基活性炭为无机相,聚丙烯酸为有机相,制备纳米孔聚丙烯酸-活性炭复合材料,并测试其对氯噻酮的吸附。发现使氯噻酮达到最大吸附值约320cm3/g的实验参数是聚丙烯酸与活性炭质量比在1∶1左右,用超声波振荡仪振荡20h,在75℃聚合反应12h,用氯仿洗涤去除未反应单体,80℃烘干10h。这种纳米孔聚合物-无机复合材料结合两者优点,在医药领域和污水净化处理等方面具有广阔的应用前景。
Firstly, rice husk-based activated carbon with high specific surface area (1000m2 / g) and average pore diameter of 50nm was prepared as inorganic phase and polyacrylic acid was used as organic phase to prepare nanoporous polyacrylic acid-activated carbon composite and its adsorption on chlorthalidone . Chlorthalidone was found to reach the maximum adsorption value of about 320cm3 / g experimental parameters of polyacrylic acid and activated carbon mass ratio of about 1: 1, shaken with an ultrasonic oscillator 20h, polymerization reaction at 75 ℃ 12h, washed with chloroform to remove unreacted single Body, 80 ℃ drying 10h. The nanoporous polymer-inorganic composite combines the advantages of both and has broad application prospects in the fields of medicine and sewage purification.
